Abstract (en)
[origin: US2015054358A1] The invention relates to a linear actuator including a driver for driving a movable assembly between a rest position and an active position, and to an electronic module for controlling the driver. The actuator further includes a damper that damps the return to the rest position of the movable assembly. The electronic module is configured to acquire a representative quantity of the instantaneous force provided by the driver and of the time derivative of this quantity. The electronic module is also able to control the interruption of the operation of the driver if the derivative exceeds a first predetermined value during the phase for returning the movable assembly to the rest position.
